The Sigma 12-24mm easily satisfies most wide-angle needs. 12mm on a 1.6x sensor is still not "ultra-wide" by 35mm standards, but the distortion level shown by the Sigma (0.22% at 12mm) is remarkably low, in fact lower than any other ultra-wide I know of - suitable for architectural photography. Edge sharpness is decent when stopped down; you'd be hard-pressed to find an ultra-wide that doesn't go a bit soft towards the edges.
Canon's 17-40mm, which I also own, is an excellent alternative...but I use the Sigma much more often because the thrill of wide-angle photography, to me, is the ability to go ultra-wide.
